中文摘要：

分别从三量子比特纯态的正则形式和Linden-Popescu-Schlienz标准形式出发，计算三量子比特纯态的紧致相对熵纠缠度及w态的紧致相对熵纠缠度．指出紧致相对熵纠缠度不具有Lu不变性，并给出它与P相对熵纠缠度之间的关系．

英文摘要：

From Linden-Popescu-Schlienz standard form and canonical form, the compact relative entropy of entanglement of 3-qubit pure state and the compact relative entropy of entanglement of W state are calculated. The fact that the compact relative entropy of entanglement is not invariant under LU transformation is pointed out, and the relation between the compact relative entropy of entanglement and the relative entropy of entanglement of Partovi is discussed.
